COSA goes on with concrete prefabrication. Here are our 42 housing units project’s facades, soon associated to our 340-space overground car park, Éco-quartier Danube, Strasbourg for Nexity. Made of raw and framed precast concrete, they reflect the mechanism of of the designs. Their fillings made of concrete smooth or sculpted with abstract patterns, and soon doors and windows with golden brown tones, give the building a subtly precious appearance.
